Abstract

Objective: In this study, we aimed to investigate the acoustic, perceptual and aerodynamic changes of voice after adenotonsillectomy by using objective methods. Methods: Thirty children, who underwent adenotonsil­lectomy surgery were included. Voice samples were re­corded 1 day before and 1 month after the surgery. Ling­WAVES programme was used as voice analysis program. Mean, maximum and minimum fundamental frequency, Jitter, Shimmer, Glottal to Noise Excitation ratio, Irregular­ity, Noise, Overall Severity, S time, Z time, S/Z ratio, and Maximum Phonation Time parameters were recorded and compared. Results: Shimmer, irregularity, Overall Severity, S/Z Time parameters were significantly lower (p=0.001) and Maximum Phonation Time significantly higher (p=0.001) in the postoperative period than preoperative period. In contrast, no significant differences were observed in the mean fundamental frequency, maximum fundamental fre­quency, minimum fundamental frequency, jitter, Glottal to Noise Excitation, S time and Z time (p>0.05). Conclusion: The changes in some acoustic, aerodynam­ic and perceptual parameters were monitored after ad­enotonsillectomy. Therefore, the families of children who underwent adeotonsillectomy should be warned for any possible changes in voice colors after surgery.

Adenotonsillektominin Akustik, Algısal ve Aerodinamik Ses Parametrelerine Etkisi

Abstract

Amaç: Bu çalışmada, adenotonsillektomi ameliyatının
sesin akustik, algısal ve aerodinamik parametreleri üzerine
olan etkilerinin objektif yöntemler ile araştırılması
amaçlanmıştır.
Yöntemler: Çalışmaya adenotonsillektomi ameliyatı yapılan
30 çocuk hasta katılmıştır. Ses analizleri operasyondan
1 gün önce ve 1 ay sonra olmak üzere 2 kez yapılmıştır.
Ses analiz programı olarak LingWAVES kullanılmıştır.
Ortalama temel frekans, Maksimum temel frekans,
Minimum temel frekans, Jitter, Shimmer, Glottal to Noise
Excitation, S time, Z time, S/Z ratio ve Maximum Phonation
Time parametreleri karşılaştırılmıştır.
Bulgular: Shimmer, irregularity, Overall Severity, S/Z
Time parametrelerinin postoperatif değerleri preoperatif
döneme göre anlamlı olarak daha düşük (p=0,001),
Maximum Phonation Time parametresi ise anlamlı olarak
daha yüksek (p=0,001) izlenmiştir. Buna karşılık Ortalama
temel frekans, Maksimum temel frekans, Minimum
temel frekans, Jitter, Glottal to Noise Excitation, S time,
ve Z time parametrelerinde anlamlı farklılık izlenmemiştir
(p>0,05).
Sonuç: Adenotonsillektomi sonrası bazı akustik, aerodinamik
ve algısal ses parametrelerinde değişiklikler izlenmiştir.
Bu nedenle adenotonsillektomi yapılacak çocukların
aileleri cerrahi sonrası gelişebilecek muhtemel ses
rengi değişikliklerine karşın bilgilendirilmelidirler
